IPLing two LPARs under one instance of Hercules

Rahim Azizarab All Messages By This Member #1360 I am curious to find out if anyone has been able to ipl two instances of any OS under Hercules when more than one CPU is defined.? I can ipl zlinux and MVS separately with the same config file but not both at the same time when I attempt a second IPL it say ? HHCPN053E ipl rejected.? I was hoping to assign each OS to a different CPU somehow. Of course I can have separate instances of HERCULES running different Operating Systems. regards; Rahim ??

Run VM, then ipl each os as a VM Guest Joe toggle quoted message Show quoted text On Sun, Jul 12, 2020 at 10:44 PM Rahim Azizarab via <rahimazizarab=[email protected]> wrote: I am curious to find out if anyone has been able to ipl two instances of any OS under Hercules when more than one CPU is defined.?

Mark L. Gaubatz All Messages By This Member #1362 开云体育 Each instance of Hercules presents an individual LPAR or BASIC mode machine. Later on, there may be controlling software that handles multiple instances of Hercules on the same physical machine, thus giving more of the appearance of a multi-LPAR machine. But for now, you have to handle each instance separately. ?

Mark Waterbury All Messages By This Member #1364 Rahim, If you load and run VM/370 as the primary OS, then you can run multiple operating systems under it, each in their own "virtual machine."? You could run DOS/360, DOS/VS, OS/360 (MFT or MVT, your choice), or OS/VS1 or MVS 3.8J ... And of course you can also have multiple users signed on to VM running CMS... all at the same time. Where do you think "LPARs" came from originally?? :-) Hope that helps, Mark S. Waterbury

Doug Wegscheid All Messages By This Member #1366 Creating paging volumes at the guest or host level?
Mark L. Gaubatz All Messages By This Member #1367 开云体育 Both. VM level such that multiple 16M guest machines can run; guest level to support added concurrent jobs within the 16M virtual machine. Huge amounts of work can be done with this scenario. MVS guests can be interconnected with virtual CTCAs along with VTAM routing. This also permits full disk sharing via full-pack minidisks in scenarios that can break Hercules’ current disk sharing methods under load. The advantage of separate instances of Hercules is that it not bounded by number of active CPUs permitted by VM/370 R6. Thus one can spread the load across more cores.

Robert Schreiber #1368 Mark is right.? When LPARs first came out every once and awhile you would get some VM errors messages as it crashed. It was originally just a VM system with the covers closed so that you didn't have to "learn" VM and could not run applications on it.
Jeff Snyder All Messages By This Member #1369 Hi Mark, Can you point me to some documentation for interconnecting 2 MVS guests using CTCs and VTAM?? I've got the CTCs genned in MVS, but haven't found any documentation yet on how to take advantage of them.? I'd prefer to work outside of VM, but I'll start there to get it working and then move it outside if I have to. Thanks, Jeff
